IRIDIUM RUDICS
|
|
|
The Iridium Router-Based Unrestricted Digital Interworking Connectivity Solution (RUDICS) is an enhanced gateway termination / origination capability for circuit-switched data calls across the Iridium satellite network.
|
|
|
Overview
|
Using Iridium RUDICS over conventional PSTN circuit switched data connectivity or mobile-to-mobile data solutions:
- Eliminates the need for analog modem training
- Increases connection quality
- Maximizes throughput and protocol independence
- Allows mobile originated and mobile terminated calls to be charged at the same rate.

How It Works
|
|
Remote applications use AT commands to
control a circuit-switched, data-capable Iridium Subscriber Unit (ISU).
The remote application dials a customer-specific Iridium number,
assigned and provisioned by Iridium, which connects the call through the
Siemens D900 switch to the RUDICS server. The ISU is authenticated
using Calling Line Identification. Once authenticated, the call is
routed over the terrestrial connection to a pre-configured Internet
Protocol (IP) address and port at the Value Added Remote (VAR) service
host application server. The RUDICS equipment supports the following
service types: TCP/IP encapsulation, PPP, and MLPP.
The host
application can make a Mobile Terminated call by opening a Telnet
session to the RUDICS server. Once this is authenticated, AT commands
connect to the remote ISU and establish a circuit-switched data call.
Connectivity between the Iridium gateway and the VAR host application
server can be via the Internet, the Internet with Virtual Private
Network, Frame Relay, or a T1/E1 Leased Line.
RUDICS also offers
capability for multi-link Point-to-Point Protocol (PPP), in which
multiple ISU’s can send data simultaneously across an N x 2400 bps PPP
connection. |
